ORCHARD-HEATER.

Specification of Letters Patent.

-lpplicaticn filed (Ecteber 19, 1912. Serial No. 726,676.

To all whom it may concern:

d it known that we, IXRRY K. FAIRALL, and Jo T CLEGHORN,

Z 7 is ot the United States, residing at land in e county ot San Bernardino is a speci- Heaters, of which the following ho I separate outlets for these recep es which open into a common casing in the evolved are co-iningled and when ignited.

a further object to provide these outvalve controlled exits and a check valve to prevent bacl: pressure ii to the receptacles,

in the drawings accompanying this specincation: Figure 1 18 a sectional elevation oi the c niplete structure, the burner being shown entirely in elevation. Fig. 2 is a *izontal cross section on the line 2 4 of cting a generator to the con is a detail section showing of the second generator or 5 is a detail axial section of in the operation of orchard burners, burning liquid fuel, ditiiculty has been experienced in etliciently burning the evolved so that clean heat is produced, so there will be no incomplete products of combustion to settle on the foliage and discolor the fruit.

This invention overcomes the above ditlicultics in providing steam to be used in conjunction with the burn' g gases, so that the combustion is complete, and the full ciliciency of the fuel is obtained, and no soot is formed to cause injury to the trees or the fruit, and the heat is disseminated more evenly and closer to the ground by suitable deflecting means.

More specifically in morals indicate the same parts in the drawings, like nuthe ditis a detail showing the terent views, 6 designating a receptacle preferably and commonly formed out of sheetinetal, having a partition 7 therein, dividing the container into two reservoirs which are closed by a common cover 8. This cover is provided with suitable flanges so that a joint is formed, and prevents the evapon of the fuel contained in one reserwhen the apparatus is not in use.

the container wo openings are proone in each of the respe'tive reservoirs, into which are introduced the outlet pipes which are preferably formed in two sections; an inner section 10, and an outer section 11. These component sections are practically of the same form and configuraexcept the means of securing the two ections together to form outlet for the respective tanks. The inner section 10 is eterably a short elbow of suitable sized p pe of non-corroding material or galvanised metal, each end being externally screw waded, the longer end of the elbow being preierably provided with the flange 12 which is threaded thereon and adapted to E rin the bearing for the latter against the wall 13 of tie reservoir.

On the projecting outer end of the section 10, a common union 1% is threaded, this exlending a suficient distance beyond the end he pipe elbow 1O receive the inner threaded end of the outer section 11. The elbow 10 extends a suitable distance within the tank, and its vertical leg is )reter bly only of such length as to receive the cap 15 which is provided with the orifice 16 in its end wall through which the fluid passes into the pipe. Before assenbling the cap 15 on the section 10, the wire stop 17 is introduced, which forms a limit for the cork or wooden check valve ball 18, this ball being contained in the valve chamber formed between the upper bend of the wire 17 and the walls of the cap and pipe. The second section 10 in the other receptacle is similarly formed with the exception that the outer clamping means is necessarily formed of one member of a coupling shown in the drawings as the threaded single portion of the coupling 19. he outer section 11 of these generators or outlets is provided with a horizontal leg of any suitable length and preferably formed with the upright limb 20 at right angles to the preferably horizontal portion of this section, this limb 20 being extended upward to a height above the height of oil and water which will be used in the accompanying reservoir, and then bent and brought down to form the limb 21 parallel with and adjacent the limb 20, the length being such that the lower threaded end is about even with the horizontal portion and placed slightly to one side so that when the two are assembled in relation to the reservoir their ends will be as close together as the valve structure added will permit. To the lower end is secured an ordinary pipe cap 22 provided with an orifice 23 in its walls, which is adapted when it is properly fitted to the threaded end of the pipe to register with the orifice 24. in the lower end of this limb 21. To provide a handle for the cap in the operation of the valve, a bore is cut through the limb, and an ordinary nail 25 is introduced, or a wire of sufficient length to reach outside the inclosing casing to the generators. These two outer sections 11 are of metal pipe and of the same form, one being the hydro-carbon gen erator, and the other the steam generator with the exception of the slight difference in the length of the horizontal limb to accommodate the slight difference in the method of coupling to their respective inner sections and the reservoir, one being capable of being threaded into the coupling 14- direct, and the other one on account of the inability to turn the same, being provided with the receiving portion of the union l9.

Surrounding and inclosing the limbs 20 and 21 of the outlets assembled in their adjacent relation, is the inclosing member 26 preferably formed of sheet metal of cylindrical form, of sufficient diameter to form a proper heating chamber, and of suflicient length as to have exit openings above the upper bend in the section 11. The lower end of the cylinder is adapted to set on the ground and is cut away at the point- 27 so that the cylinder will straddle the horizontal portions of the sections 11 and of sufficient height as to clear the valve handles, and not interfere with their efficient movement.

The upper end of the member is serrated, as shown, by a plurality of V slots 28, and the material left, preferably flared down from the apex of the serrations outward. At a proper distance below the apexes of the serrations 28, a series of openings 29 are cut in the walls of the cylinder, this distance below the serrations being determined by experiment as well as the size of the orifice, the latter forming the draft opening for the entrance of air. The flaring outer ends of the projections formed between the serrations, are formed as near level as possible to provide a shelf for the circular deflecting plate or cover 30 preferably of metal, and formed of considerably greater diameter than the cylinder 26.

In the operation of this device oil of an inflammable nature, preferably a heavy distillate, is placed in one of the reservoirs, and water in the other, the valves 22 being opened, the pressure of the fluids is sufficient to depress the balls 17, and allow the fluids to flow to the same level in the limb 20 as in the reservoirs. A small amount of inflammable oil or hydro-carbon is now dropped on the ground within the cylinder 26 and ignited, or a torch may be used, until the gas is generated, by the vaporization of the oil in the oil limb 20. When the gas so generated escapes through the valved orifice and becomes ignited, the heat and flame will pass out through the orifices 28 and under the plate 30 which is placed in position immediately after the ignition of the initial heating means. At the time when the heat is sufhcient to vaporize the water in the other up-right limb, steam will issue in a stream from its orifice and co-mingling with. the gases escaping from the adjacent valve will increase the draft and the breaking up of the steam into its original elements will add further gases which as well known, are smokeless, and joining with the gases evolved from the hydro-carbon together with the oxygen in the air from the draft openings, results in an absolutely sootless and smokeless flame surrounding the edges of as well as in the cylinder,heating the vertical limbs 20 and 21 and continuing the operation of generation, the flame issuing from the casing in the most efficient and desirable form.
